1 Claim.

The present invention relates to a novel fitting and method ofmanufacture of a hose connection for a radiator header.

The principal object of my invention is to provide a fitting which ismade from the same kind of material and having about the same thicknessas the thickness of the header tank material, the rear panel of the tankhaving a horizontally elongated opening which is surrounded by thefitting and having an area somewhat larger than the area of the tubepart of the fitting, whereby expansion and contraction between thecontacting parts will be similar and, whereby turbulence will be reducedto a minimum thusto avoid resistance to the flow of the liquid.

In forming or drawing thin metal parts, it is necessary to avoiddamaging the material at bends and where the material is stretched. Inthe present invention the shape of the parts is such as will insureagainst such damage.

Generally stated, objects of my invention are toprovide fittings of thecharacter which are attractive, strong, efiicient and easilymanufactured at low cost.

It will be understood that the present invention is largely adapted. forthe inletconnection of the top header of a radiator. However it may beused as an outlet connection on the bottom header of a radiator and inheaders having a somewhat different shape than shown.

To these and other useful ends my invention consists of parts,combinations of parts or their equivalents and method of manufacture,assembling and attaching to the header as described and claimed andshown in the accompanying drawings in which:

Fig. 1 illustrates a partially sectioned upper header for a radiator,the section being through the fitting.

Fig. 2 is a rear view of the fitting as shown in Figure 1 showing afraction of the header.

Fig. 3 is a top view of the fitting as shown in Figures 1 and 2 showinga fraction of the header.

Fig. 4 is a side elevational view of a modification and illustrating afraction of a header.

Fig. 5 is a transverse sectional enlarged view of the fitting shown inFigure 4 and illustrating a fraction of the header.

The upper header for a radiator is generally considerably wider than thewidth of the lower headers. This is done principally in order to providecapacity for the water or cooling fluid. In Figure 1 an upper header isshown and designated in its entirety by reference character A and thetube plate of the header is designated by 2 reference numeral H. The topand bottom headers of radiators are generally connected together bymeans of flattened tubes I2 having closely spaced fins (not shown)through which the tubes extend.

Header A generally has a filler cap I4 which is attached to a tube IS,the tube being secured to a raised portion generally on the longitudinalcenter of the header. The rear side of the header, particularly at thelongitudinal center thereof is preferably ofiset downward as at l6forming atop plate l'!, the rear plate of the header being designated bynumeral I81. Before the header is assembled by adding the tube plate,the top portion of the header is generally called the tank, thereforemembers l4 through l8 may be considered as parts of the tank of theheader.

I provide preferably a bracket I9 which is positioned as shown andsecured to member I! as a rest for the hood or covering for the engine.Rear tank plate I 8 has an opening 20. This opening is considerablylonger than its width for a purpose which will hereinafter appear.

My improved fitting in its entirety is designated by reference characterB and includes a short tube 25 having preferably a raised portion 26around its periphery adapted to more firmly grip the hose connection 21.This member is made from substantially the same kind and thickness ofmaterial as the header tank. The other part of member B consists of amember 28 formed preferably from a flat sheet of the same material asthe tank and having about the same thickness.

Member 25' has a shape about as shown in the figures, the upper endhaving a flange 29. Its forward edge 38 is bent downward and is adaptedI to lie against plate H! as clearly shown in Figures 1 and 2. Flange 29has formed thereon an upwardly extending flange 3| which is formedintegrally with flange 29 and member 30.

Member 28 has a shape about as shown in the figures, having a flange 36around its bottom surface which is formed integrally with a flange 31and adapted to be on the same plane as flange 30, so that flanges 35 and37 surround three sides of opening 26. Flange 31 is formed integrallywith the top of member 28 which is extended forward over panel I! anddesignated by numeral 39. An offset 38 in the connection between members28 and 39 is adapted to lie on the curved surface of the tank, thusforming an excellent surface for bonding the contacting surfacesadjacent opening 20. An opening at 43 and another opening in member 39which corresponds with the opening at 40 is provided for the receptionthus forming a leak proof joint between fitting B and the tank of headerA.

It will be seen that the three rivets at 49 will firmly hold the fittingto the tank while being bonded thereto and because flanges 39 and 39 areriveted and bonded to the outer surfaces of members i1 and [8, a firmjoint is made between the fitting and the tank; that the fiow of liquidfrom tube 25 into the header will be free and accomplished with littleturbulence or resistance; that expansion and contraction between thecontacting parts will be similar, thus to avoid fractures of thematerial or loosening of the bonded joints and as recited in thepreamble of this specification, the fitting will have a pleasingappearance, be light and strong and can be manufactured at low cost.

In Figures 4 and I illustrate a fitting that is somewhat similar to thefitting shown in Figures 1, 2 and 3 which in its entirety is designatedby reference character C, comprising a main body 4 I, the forward partof which is oblong as in Figures 1, 2 and 3. In these figures the tankis designated by reference numeral 42, the tube plate by numeral 43 andthe tank bracket by numeral 44. The rear plate of the header tank isdesignated by reference numeral 45 and the top plate of the header isdesignated by numeral 46. A flanged opening 41 is shaped about likeopening 20 in Fi ures 1, 2 and 3 except the opening is slightly lowerand provided with an inwardly turned flange adapted to fit around theadjacent portion of member 4| as illustrated in Figure 5. The upperfront end of member 4| is offset upwardly as at 48 and forming a surface49 adapted to lie on the underside of top plate 46 of the tank and isriveted to this surface by a rivet 50, thefront edge of member 4| beingcut away as at 51 forming a shape which can be inserted into opening 47.After rivet 59 is applied, the fitting is held firmly into position,after which the flange of opening 41 and plate 45 is bonded to member4|. Member 4| is rounded at its rear end forming an opening whichextends rearwardly and downwardly into which a short tube 52 is insertedand bonded thus forming a surface similar to the lower end of tube 25 inFigures 1, 2 and 3.

It will be noted that Figure 4 is about the same scale as Figures 1, 2and 3 and that Figure 5 is somewhat enlarged; that member 39 and itsrivet as shown in Figures 1, 2 and 3 operate very similar to extension49 and rivet 50 in Figures 4 and 5 and in a manner which after therivets have been set and the joints bonded, to provide a very strongfastening between the tank and fitting. Thus clearly applicants fittingswill meet the requirements set forth in the preamble of thisspecification.

It will be understood minor detail changes may be made in the designshown without departing from the spirit and scope of my invention asrecited in the appended claim.

Having thus shown and described my invention, I claim:

A hose connection fitting for a radiator tank having an opening in itsrear panel, comprising in combination, an inverted cup shaped memberformed with front and bottom edges, said front and bottom edges havingintegrally formed thereon outwardly extending front and bottom flanges,the front flange being adapted to register with the top and sides ofsaid opening, having a portion of the top edge of the front flangeextended forward and adapted to lie on the top panel of the tank, theentire front flange being bonded to the rear and top panel of the tank,another member comprising a tube, having on its upper end an outwardlyextending flange, a portion of the front edge thereof being extendeddownwardly and adapted to lie on the rear panel of the tank and adjacentthe bottom of said opening and being bonded to the rear tank panel andto the bottom edge of said front flange, its remainder being bonded tothe bottom fiange of said cup shaped member, forming a leak proofconnection between the tube of said other member and the interior ofsaid tank.
